2 Claims.

This invention relates to guide supports for spools on which thread is Wound for textile purposes, and is a division of a prior application, Serial No. 262,687, filed by me March 18, 1939, Patent No. 2,211,078.

It is the general object of my invention to provide an improved guide support, so designed that the spool may be readily inserted in its supports and as readily removed therefrom.

A further object is to provide a guide support having improved means to prevent axial lost motion of the spool during a winding operation.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a sectional end elevation of parts of a winding machine embodying my improvements;

Fig. 2 is a partial front view, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a side elevation, partly in section, showing a spool frame and spool sleeve partly separated; and

Figs. 4 and 5 are detail sectional views, taken along the lines 44 and 5-5 in Fig. 1 respectively.

Referring to Fig. 1, I have shown portions of a winding machine including a rail H1 supporting brackets H which provide spaced bearings for a winding shaft I 2 which drives a plurality of axially-spaced winding rolls i3. The brackets H also uphold a cross bar l5, to which guide supports 16 for the winding spools are secured by clamping bolts 11.

Each guide support comprises a fixed framemember or stand 20 having a substantially vertical guide groove 2! (Fig. 4) in one face thereof and a rectangular recess 22 in the opposite face. A block 24 is loosely mounted in the recess 22 but is secured from outward displacement by headed studs 25 fixed in the frame member 20.

Coil springs 25 are interposed between the block 24 and the member 28 and hold the block 24 yieldingly in the outward position shown in Figs. 4 and 5. The springs 26 are seated in aligned recesses 21 and 28 in the frame member 29 and block 24 respectively. A guide groove 29 is provided in the block 24, which groove is aligned with the fixed guide groove 21 previously described.

The spool S is supported on a shaft 353 (Fig. 3), the ends of which are received in guide grooves 2| and 29 in adjacent supp ts when the sp l is in winding. position. A. pin.3l in one end ofthe shaft 30 engages a side wall of the associated guide groove and holds the shaft 30 from rotation. The end of each shaft 30 which is in a groove 29 is yieldingly engaged by a movable block 24, so that axial lost motion of the spools is eliminated.

The spool S may comprise a spool frame F, and a sleeve V on which the thread T is wound. The spool frame F is preferably formed with dished sheet metal heads 33 and 35, secured in fixed axial relation by longitudinal connecting members 35, and is rotatably mounted on the shaft 39.

The sleeve V may be of any suitable sheet material, such as vulcanized fibre or a synthetic resinous material, and is designed to slip easily over the heads 34 and 33 and to be positioned axially by an end flange 40 on the head 33.

Driving levers 43 are pivoted in the frame F and the free ends of said levers project through a slot 44 in one end of the frame.

Pointed studs 48 are mounted in the levers 43 in the frame F and may be yieldingly projected outwardly through openings 49 in the associated members 35. The pointed studs 48, when thus outwardly projected, are in holding and driving relation with the sleeve V assembled on the frame. F, and prevent either longitudinal or axial displacement thereof. The studs 48 may be withdrawn by grasping the free ends of the levers 43.

The spools are mounted between pairs of guide supports I5, and each spool S, or the thread T wound thereon, engages one of the driving rolls [3 and is continuously rotated thereby. As the mass of thread increases in diameter, the spool moves freely upward, but is guided and retained in position by the grooves 2| and 29 in the supports l6.

Each fixed frame member or stand 20 has a forwardly projecting hook portion adapted to receive and freely support the bearing shaft 30 of a full spool S after removal of said spool from winding position.

After the desired amount of thread has been wound on a spool S, the spool may be removed by insertingthe fingers into the recessed spool heads and lifting the spool shaft 30 out of the guide grooves 2i and 29. As this movement is approaching completion, the ends of the shaft 30 engage guard plates (Fig. 1) on the upper ends of the supports I6, so that further movement must be forward as well as upward. The filled spool is thus kept clear of contact with adjacent parts of the machine.

After a spool S has been thus'removed, the operator separates the full sleeve V from. the frame F and supplies the frame with an empty sleeve. It will be evident therefor that the number of spool frames Fneed be sufficient only to fill the winding machine, while sleeves V are provided for any required number of thread packages.

ing spools each having a shaft on which. the

spool is mounted, and a plurality of guide supports for said spool shafts, each support guiding the adjacent ends of two'spool shafts and each support comprising a stand having a guide groove in one side, a grooved guide plate loosely mounted in the recessed other side of said stand, a plurality of spaced compression springs operative to move said plate toward the end of an associated spool shaft, and a plurality of spaced headed studs fixed in said stand and which position said plate and limit outward movement thereof.

2. In a winding machine, a plurality of winding spools each having a shaft on which the spool V is mounted, and a plurality of guide supports for said spool shafts, each support guiding the adjacent ends of two spool shafts and each support comprising a stand having a straight guide groove in:one side, with that face of said groove which is engaged by the outer end face of the spool shaft disposed in a plane perpendicular to the axis of the supported spool shaft, a guide plate loosely mounted in the recessed other side of said stand and having a guide groove substantially parallel to said first groove, and means in said stand to press said plate outward against the end of an associated spool shaft, thereby eliminating end play thereof.
